Subject [jira] [Commented] (YARN-2139) [Umbrella] Support for Disk as a Resource in YARN
Date Sat, 22 Nov 2014 00:57:38 GMT

    [ https://issues.apache.org/jira/browse/YARN-2139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14221669#comment-14221669

Wangda Tan commented on YARN-2139:
----------------------------------

Thanks [~bikassaha] and [~kasha],

+1 for work on a branch, there might be some great amount of changes across all the major
modules, frequently rebasing might be a issue if this is based on trunk.
And also totally agree about having an abstract policy to wrap disk affinity / iops / bandwidth,
etc.

> YARN should consider disk as another resource for (1) scheduling tasks on nodes, (2)
isolation at runtime, (3) spindle locality.
